Gluster users - Jul 2013 - Mounting localhost vs. remote host

Hi,

What is better?  Is making a client part of the cluster and then making the
mount via "localhost":

# service glusterd start
# gluster peer probe somehost
# mount -t glusterfs localhost:/volume /mnt/temp

or:

# mount -t glusterfs somehost:/volume /mnt/temp

I guess with mounting it via somehost, one would have to very picky to
choose which host to pick as if it goes down that mount may stop working.
 Am I correct?  So what is better?

Thanks,

Ziemowit

Another option is to use round-robin dns to make a single hostname point 
to all your gluster servers: 
http://edwyseguru.wordpress.com/2012/01/09/using-rrdns-to-allow-mount-failover-with-glusterfs/.
This gives you a single hostname to mount through, while still working 
fine when some of your servers are down for maintenance.

I've had real trouble mounting anything from localhost on boot, whereas
remote works fine. Search the list archives.
